Abstract
A computer-implemented method, executed by one or more email detection computers, receives from a computer network, a first email message from a first sender account to a first recipient account and having a plurality of attributes. The method determines that the first email message is a phishing email, extracts a subset of attributes, normalizes transformable attributes, and generates a hash representation from fixed attributes and the normalized transformable attributes, stores the hash representation in a database, receives a second email message, and determines that the second email message is a phishing email based on the stored hash representation.
